METAL AWN ING.

Specification of Letters Patent No. 20,085, dated April 27, 1858.

To all whom it may concern:

Be it known that l, VILLIAM O. PARrsnN, of the city, county, and State of New York, have invented a new and Improved Metal Awning; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is an end view of a metal awn ing in a distended state constructed according to my improvement. Fig. 2, is a back view of ditto in an open state, showing the inner side of the awning. Fig. 3, is an end view of ditto in a closed state. Fig. 4, is a detached perspective view of the ends of t-wo metal plates or strips.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in the employment or use of a series of metal plates or strips so arranged as to lap one over the other, each plate being fitted between guides which are attached to the lower ends of the plate immediately above it, and the plates connected to toggles which, in connection with arms and a windlass, allow the plates to be raised and folded together when an awning is not necessary, or to tall and be distended when an awning'is required.

To enable those skilled in the art to fully understand and construct my invention l will proceed to describe it.

A, may represent pillars at the side of a building' or house, or the side of a building which the awning is to shade.

B, represents a series of metal plates which form the awning. These plates are constructed ot sheet metal. Galvanized iron, or Zinc, will probably be the material used. The plates extend the whole width of the building or are equal in length to the space designed to be shaded by the awning, and are comparatively narrow in width say from 12 to 1S inches. Each plate is strengthened or rendered sti by a wire a, around which wires the upper ends of the plates are closed and the lower end of each plate has two metal strips Z), attached to it, one at each side, said strips projecting beyond the sides of the plates and curved or bent around underneath the plates as shown more particularly in Fig. 4. The strips b, serve as guides, the strips of each plate passing around the sides of the plate immediately below it, the plates overlapping each other as shown in all the figures. The upper plate is secured to the side of t-he building by means of the staples or hooks c.

C, C, are two toggles, the levers d, e, of which are attached, one, cl, of each toggle to the building by the staples or hooks c, and the other c, to the lower plate B, as shown at f. The toggles are placed one near each end of the plates B, and the toggles are connected by a chain D, the ends of which are attached to them at the junction of their levers, as shown clearly in Fig. 2. Each toggle 4C, at the junction of its levers has an arm E, attached to it by a pivot and the lower ends of these arms are pivoted to. a rod F, which projects horizontally from the building about in line with the center of the awning as shown clearly in Fig. l. Each lever e, of the toggles has the upper end of an arm G, pivoted to it, and the lower ends of these arms are pivoted to horizontal arms H, attached to the building.

I, is a windlass which is attached to the building and in line with one end of the awning. This windlass has two ropes or chains g, 7L, wound around its drum in opposite directions. The upper partot the rope or chain g, passes through a sheave z', attached to the building and is connected at one end to the lower plate B, and a branch rope or chain g, is attached to g, the rope or chain g', passing through a sheave i', and extending horizontally along the building'to a sheave i, through which it passes and is attached to the opposite end of the lower plate B, see Fig. 2. The rope or chain it, passes through a sheave j, also attached to the building and also passes through a sheave L", attached to the nearest toggle O, said rope or chain then passing through a sheave Z, attached to the end of the awning and then passing back, is permanently attached to sheave see Fig. 2. The rope or chain z., has a branch rope or chain m, attached which passes horizontally along the building and through a sheave j', and also through a sheave j, connected to the other toggle C, at the junction of its levers and then passing through a sheave n, at the end of the awning and passing back is attached to sheave j.

From the above description of parts it will be seen that by turning the windlass I, in the direction indicated by arrow l, the plates or strips B, will be raised or folded together as shown in Fig. 3, for as the ropes or chains g, g, draw up the lower plate B, the ropes or chains h, m, are correspondingly slackened or unwound from the windlass, and the toggles C, C, are allowed to bend or fold inward. 1When the windlass I, is turned in the opposite direction as indicated by arrow 2, the rope or chain g, is unwound from the windlass while the rope or chain h, is wound upon it, and the toggles C, C, will be straightened by the ropes or chains h, m, said toggles unfolding the plates B, and distending the awning. The chain D, limits the outward movement of the toggles.

Awnings constructed according to the within described invention will be extremely durable and they will not much exceed, if at all7 the cost of the usual canvas ones, in connection with the frames used to support them, Y

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is,

The metal plates or strips B, so arranged that one may overlap the other, and kept in proper position `by guides Z), when said plates are used in connection with Atoggles C, C, and arms E, E, G, anda windlass I, arranged so as to raise and lower or, fold or unfold the plates substantially as and for the purpose set forth.
